How can I check my Audi's engine oil level?

I just bought an Audi and I want to make sure I maintain it correctly. How can I check the engine oil level?

To check your Audi's engine oil level, park your car on a level surface and wait for the engine to cool down. Open the hood and locate the engine oil dipstick. Pull out the dipstick and wipe it clean with a cloth. Reinsert the dipstick, fully seat it, and pull it out again. The oil level should be between the two marked lines. If it's below the minimum line, add the recommended oil. If it's above the maximum line, have your car inspected by a mechanic.
